Description

    Granite v-block is crisp,so it is afraid of hard hit.As the result,we should use it carefully.We'd better prevent some heavy things hitting the v-blocks,lest occuring sags and crests.
   If we don't use it for a long time,we should wipe it with the special lubricants.If there isn't special lubricants,it can be replaced by cooking oil.Just dry again with a soft cloth when we use it next time.
